RESUMO
Hip hemiarthroplasty is a commonly performed orthopedic surgery, used to treat proximal femur fractures in the elderly population. Although hip hemiarthroplasty is frequently successful in addressing these injuries, complications can occur. Commonly seen complications include dislocation, periprosthetic fracture, acetabular erosion, and leg-length inequality. Less frequently seen complications include neurovascular injury and capsular interposition. This article presents a comprehensive review of the complications associated with the management of hip hemiarthroplasty. [Orthopedics. 2023;46(4):e199-e209.].

BACKGROUND: Suprapatellar nailing of tibial fractures has not been shown to affect short-term knee outcomes, however long-term outcomes are unknown. The purpose of this study was to report long-term patient-reported knee outcomes after suprapatellar nailing. METHODS: Thirty-five adult patients with 37 tibial shaft fractures treated with suprapatellar nailing completed the Tegner-Lysholm Knee Score (TLKS) at an average of 5 years (range, 4-9 years) follow-up. RESULTS: The median TLKS was 98 (interquartile range, 85-100): Scores were considered excellent in 24 (68%), good in 3 (9%), fair in 3 (9%), and poor in 5 (14%). Based on patient responses, 28 (80%) patients did not have a limp, 32 (91%) ambulated without assistance, 22 (63%) were pain free, 29 (83%) had no knee instability, 30 (86%) endorsed no catching or locking, 27 (77%) could climb stairs with no issue, and 24 (69%) had no problems with squatting. Patients with poor/fair outcomes on the TLKS were more likely to have had a complication [3 (38%) vs. 1 (4%), difference 34%, 95% confidence interval 1-65%] and had no detectable difference in age, gender, open fracture, fracture classification, or worker's compensation. CONCLUSION: At long-term follow-up a majority of patients undergoing suprapatellar nailing had good/excellent knee outcomes. Poor/fair knee outcomes were associated with the development of complications. LEVEL OF EVIDENCE: III, Retrospective cohort study.
RESUMO
BACKGROUND: Intramedullary nail (IMN) fixation of the fibula in malleolar ankle fractures has been shown to result in less wound complications then plate fixation. Therefore, IMN fibula fixation may also be associated with lower rates of wound complications when used for higher-risk pilon fractures. The purpose of this study was to compare complications of fibula IMN fixation in pilon versus malleolar ankle fractures. METHODS: A retrospective cohort comparison was performed at an urban level one trauma center involving fibula fractures in 47 patients with AO/Orthopaedic Trauma Association (OTA) type 43 fractures and 48 patients with AO/OTA type 44 fractures being treated with fibula IMN fixation. Complications, fibula-specific complications, revision surgeries, and implant removals were reviewed. RESULTS: There was no detectable difference in complications (27% vs. 23%, 95% confidence interval of the odds ratio (CIOR) 0.5 to 3.2), fibular-specific complications (6% vs. 10%, CIOR 0.1 to 3.5), revision surgeries (4% vs. 4%, CIOR 0.1 to 7.5), or symptomatic fibula implant removals (13% vs. 21%, CIOR 0.1 to 1.6) between pilon and ankle fracture groups, respectively. There was one (2%) fibular nonunion and one wound complication (2%) in each of the fracture groups. CONCLUSION: Fibula IMN fixation of pilon versus ankle fractures resulted in a similar number of complications. Comparative studies of fibula IMN and plate fixation are necessary to determine if the benefits of fibula IMN in ankle fractures extends to pilon fractures. LEVEL OF EVIDENCE: Level III, retrospective cohort.
RESUMO
BACKGROUND: The standard proximal interlocking screw (SS) configuration for antegrade intramedullary nail (IMN) fixation of femoral shaft fractures is lateral to medial or from the greater to less trochanter. Some authors argue for the routine use of the reconstruction screw (RS) configuration (oriented up the femoral neck) instead to prevent femoral neck complications. The purpose of this study was to compare a matched cohort of patients receiving these screw configurations and subsequent complications. METHODS: A retrospective review of two urban level-one trauma centers identified adults with isolated femoral shaft fractures undergoing antegrade IMN. Patients with RS and SS configurations were matched 1:1 by age, sex, fracture location, and AO classification in order to compare complications. RESULTS: 130 patients with femoral shaft fractures were identified. SS and RS configurations were used in 83 (64%) and 47 (36%) patients. 30 patients from each group were able to be matched for analysis. The RS and SS group did not differ in age, fracture location, AO classification, operative time, or number of distal interlocking screws. The RS group had fewer open fractures and were more likely to have two proximal screws. There were 7 complications, including 5 nonunions and 2 delayed unions, with no detectable difference between RS vs. SS groups (10% vs 13%, Proportional difference -3%, 95% confidence interval (CI) -30 to 14%, p = 0.1). There were no femoral neck complications in the entire cohort of 130 patients. On multivariate analysis none of the variables analyzed were independently associated with the development of complications. CONCLUSIONS: In this matched cohort of patients with femoral shaft fractures undergoing antegrade IMN fixation, RS and SS configurations were associated with a similar number of complications and no femoral neck complications. The SS configuration remains the standard for antegrade IMN femoral shaft fixation. LEVEL OF EVIDENCE: Level III, Retrospective cohort study.
RESUMO
INTRODUCTION: The purpose of this study was to determine if varus displacement of intertrochanteric femur fractures on injury radiographs is associated with screw cutout after fixation. METHODS: A retrospective review performed at two urban level 1 trauma centers identified 334 patients with intertrochanteric femur fractures treated with either a cephalomedullary nail (CMN) or a sliding hip screw (SHS). Median patient age was 75 years, 69% were female and 46% had unstable fractures. Varus fracture displacement on injury radiographs, defined as the most proximal aspect of the femoral head being at or below the most proximal aspect of the greater trochanter, was present in 38% of patients. Screw cutout was recorded. RESULTS: Varus displacement was associated with unstable fracture patterns (62% vs. 37%, difference (D) 25%, 95% confidence interval (CI) 15-35%), female gender (77% vs. 64%, D 13%, CI 3-22%) and poor/adequate reductions (54% vs. 41%, D 13%, CI 2-23%). Cutout occurred in 9 (3%) patients, 8 of which had varus displacement. There was no detectable difference, with wide confidence intervals, between patients that did and did not experience cutout in terms of age, gender, unstable fractures, implants, tip-apex distance (TAD) or poor/adequate reductions. On univariate and multivariate analysis, varus displacement was the only variable associated with cutout. Patients with and without varus displacement had a cutout incidence of 6 and 0.5% (Odds ratio 13, CI 1.6-108). CONCLUSION: Intertrochanteric fractures presenting with varus displacement were more likely to experience cutout. This potential risk factor for cutout warrants further study. LEVEL OF EVIDENCE: Level 3, retrospective cohort.

BACKGROUND: The majority of clavicle fractures are midshaft injuries, although fractures of the distal or medial fragment also occur. The aim of this study was to review the current evidence on these injuries to help inform future treatment plans. METHODS: We searched for studies comparing interventions for medial, midshaft, or distal clavicle fractures; however, we did not identify any comparative studies on medial fractures and performed a secondary search on this topic. We conducted Bayesian network meta-analyses, although this was not feasible with studies on medial fractures and we described their results qualitatively. RESULTS: For midshaft fractures, we found statistically significant improvements in function and time to radiographic union with plating, an elastic stable intramedullary nail (ESIN), and the Sonoma CRx intramedullary nail over nonoperative treatments. Both plating and an ESIN also showed significantly lower risks of nonunion and malunion relative to nonoperative methods. For distal fractures, a locking plate (LP) with or without coracoclavicular (CC) suturing yielded significantly better outcomes over K-wires with or without tension bands, CC suturing alone, an LP with a CC screw, a hook plate, and a sling. For medial fractures, plating may result in more favorable functional and union-related outcomes, although implant irritation may occur. In addition, K-wires, tension bands, and a screw with sutures demonstrated success when plating was technically not feasible in a few cases, whereas treatment with a sling may result in reduced function and a higher risk of complications relative to surgery. CONCLUSION: This study can provide guidance on the management of medial, midshaft, and distal clavicle fractures. The current evidence suggests that plating, an ESIN, and a CRx intramedullary nail are all good options for midshaft fractures; an LP with or without CC suturing should be preferred for distal fractures; and plating is also acceptable for medial fractures, provided that the patient is deemed suitable for surgery and has the adequate bone stock and sufficiently sized medial fragment necessary to implant the device. Patient preferences for certain outcomes should be considered, which may result in different treatment recommendations.
RESUMO
Dynamization of fracture fixation constructs provides early rigidity for primary bone healing and late motion for secondary healing. A review of laboratory, animal, and clinical studies investigating the impact, and optimal timing, of dynamization is limited by lack of standardization across studies. However, in animal models, dynamization improves histologic and biomechanical properties compared with statically rigid or flexible controls. In animals, dynamization at 3 to 4 weeks showed improved histologic results. In clinical studies, it showed faster, stronger, and stiffer bone healing. Clinical success dynamizing external fixators and intramedullary nails suggests a role for late dynamization in other fixation types, such as bridge plating. [Orthopedics. 2020;43(3):e125-e133.].

OBJECTIVES: To evaluate variables associated with lag screw sliding after single-screw cephalomedullary nail (CMN) fixation of intertrochanteric femur fractures. DESIGN: Retrospective cohort study. SETTING: Level-one trauma center. PATIENTS/PARTICIPANTS: One hundred fifty-eight intertrochanteric fractures in patients older than 65 years with an average follow-up of 22 months. INTERVENTION: Single-screw CMN fixation. MAIN OUTCOME MEASUREMENTS: Lag screw sliding and revision surgeries. RESULTS: The average amount of lag screw sliding was 5 ± 5 mm (range, 0-21 mm). Lag screw sliding was greater with unstable fracture patterns (mean difference 2 mm, 95% confidence interval 0.4-3.5 mm, P = 0.01) and calcar gapping >4 mm (mean difference 3.7 mm, 95% confidence interval 2-5 mm, P < 0.01). No association was found between lag screw sliding and age, female gender, implants, long versus short nails, distal interlock screw use, postoperative neck-shaft angle, or tip-apex distance (P > 0.05). Revision surgeries were performed in 6 (4%) patients. Indications included symptomatic lag screw removal (n = 2), avascular necrosis (n = 1), cutout (n = 1), loss of reduction (n = 1), and perimplant fracture (n = 1). CONCLUSIONS: Unstable fracture patterns are unavoidable; however, careful attention to calcar reduction and selection of dual-screw CMN implants may minimize lag screw sliding and its detrimental effects on outcomes. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVES: To compare cell salvage (CS) volume, intraoperative blood loss, intraoperative blood transfusions, and operative time for acetabular fractures undergoing early (≤48 hours from admission) versus delayed fixation (>48 hours from admission). DESIGN: Retrospective. SETTING: Level one trauma center. PATIENTS: One hundred thirty-one patients with unilateral acetabular fractures involving at least one column. INTERVENTION: Open reduction and internal fixation performed through the anterior intrapelvic approach or posterior approach. MAIN OUTCOME MEASUREMENTS: CS volume, estimated blood loss (EBL), intravenous fluids (IVFs), intraoperative packed red blood cells (PRBCs), and operative time. RESULTS: Early versus delayed fixation through the posterior approach was associated with shorter operative times and less intraoperative PRBCs (140 vs. 301 mL, MD -161 mL, 95% confidence interval -25 to -296 mL) with no differences in CS, EBL, or IVF. Early versus delayed fixation through an anterior intrapelvic approach was more common in less severe fracture patterns with no differences in PRBCs, CS, EBL, or IVF. CS, through either approach, was successful in returning blood to 77% of patients for an average of 267 ± 168 mL (range, 105-900 mL). CONCLUSIONS: Fixation of acetabular fractures within 48 hours of admission did not increase blood loss or intraoperative transfusions. CS was successful in returning an average of one unit of blood to a majority of patients. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

INTRODUCTION: Injuries to the critical structures underlying the clavicle are possible during open reduction and internal fixation (ORIF) and afterward secondary to prominent screws. The purpose of this study was to identify patients who received chest computerized tomography (CT) scans after clavicle ORIF to evaluate the distance between the screws and the subclavian vessels. METHODS: A retrospective review was performed at a single level-one trauma center. Nineteen patients with chest CT scans after superior plate fixation were included. Coronal CT reconstructions were analyzed to determine distances between the subclavian vessels and screw tips along with the prominence of the screws. Vessels within 15 mm of the screw were considered at risk. RESULTS: None of the screws (0/142) were within 15 mm of the subclavian vessels. Average screw prominence was 1.3 ± 1 mm (range, 0-3.6 mm). One of the 19 patients had a complication, a re-fracture requiring revision ORIF. The remaining 18 patients had no complications, including neurovascular or pulmonary, at the last follow-up. CONCLUSIONS: None of the screws were excessively prominent or within 15 mm of the subclavian vessels. Attentive superior plate fixation of the clavicle with screws is a safe technique. LEVEL OF EVIDENCE: Level IV, case series.

INTRODUCTION: The burden that family and friends assume when caring for hip fracture patients can negatively impact the caregiver's quality of life, relationships, and the decision to place the patient in a care facility. The purpose of this study was to evaluate the burden of caregiving for intertrochanteric hip fractures to better counsel patients and caregivers in order to prevent delayed admission to a care facility. METHODS: A retrospective analysis of a prospectively gathered elderly hip fracture database identified 29 patients and their caregivers with complete 6 month follow-up. Caregiver burden and depression scales were administered to the primary caregiver in the immediate perioperative period (baseline), at 3 month follow-up, and at 6 month follow-up. At each time point caregivers reported the effects of caregiving on their finances, work hours, relationships, and their willingness to admit the patient to a long-term care facility. RESULTS: At 6 month follow-up, <30% of caregivers reported negative effects on their finances, relationships, work hours, or intent to place the patient in care facility, while 77% endorsed cherishing their time spent as a caregiver. The number of caregivers with a high caregiver burden remained stable at 20% over the 6 month follow-up; these caregivers were more likely to have a depressed mood (pâ¯<â¯0.01), to consider placement of the patient into a long-term care facility (pâ¯<â¯0.01), and to have negatively affected finances (pâ¯=â¯0.03) and relationships (pâ¯<â¯0.01). CONCLUSIONS: High degrees of burden were experienced by 20% of caregivers of hip fracture patients. Caregivers with high caregiver burdens were more likely to consider placement of the patient into a long-term care facility. Risk factors for high caregiver burdens should be identified to optimize the quality of caregiving after discharge and to prevent delayed admission to a long-term care facility. LEVEL OF EVIDENCE: Level IV, case series.

OBJECTIVE: Needlestick and sharps injury (NSSI) is a common occupational hazard of orthopedic surgery training. The purpose of this study was to examine the incidence and surrounding circumstances of intraoperative NSSI in orthopedic surgery residents and fellows and to examine postexposure reporting. DESIGN: A 35-question cross-sectional survey. SETTING: The study was conducted by orthopedic surgery residents and faculty at a nonprofit regional hospital. PARTICIPANTS: The questionnaire was distributed to US allopathic orthopedic surgery residency and fellowship programs; 300 orthopedic surgery trainees participated in the survey. RESULTS: Of 223 trainees who had completed at least 1 year of residency, 172 (77.1%) sustained an NSSI during residency, and 57 of 63 trainees (90.5%) who had completed at least 4 years sustained an NSSI during residency. The most common causes of NSSI were solid needles, followed by solid pins or wires. The surgical activity most associated with NSSI was wound closure, followed by fracture fixation. The type of surgery most frequently associated with NSSI was orthopedic trauma, followed by hip and knee arthroplasty. Of 177 trainees who had sustained a prior NSSI, 99 (55.9%) failed to report all events to their institution's occupational health department. CONCLUSIONS: The incidence of NSSI during residency training is high, with >90% of trainees in their fifth year or later of training having received an injury during their training, with a mean of >4 separate events. Most trainees with an NSSI did not report all of their events, which implies that changes are needed in the incident reporting process universally.

Importance: Disability persists after hip fracture in older persons. Current rehabilitation may not be sufficient to restore ability to walk in the community. Objective: To compare a multicomponent home-based physical therapy intervention (training) with an active control on ability to walk in the community. Design, Setting, and Participants: Parallel, 2-group randomized clinical trial conducted at 3 US clinical centers (Arcadia University, University of Connecticut Health Center, and University of Maryland, Baltimore). Randomization began on September 16, 2013, and ended on June 20, 2017; follow-up ended on October 17, 2017. Patients aged 60 years and older were enrolled after nonpathologic, minimal trauma hip fracture, if they were living in the community and walking without human assistance before the fracture, were assessed within 26 weeks of hospitalization, and were not able to walk during daily activities at the time of enrollment. A total of 210 participants were randomized and reassessed 16 and 40 weeks later. Interventions: The training intervention (active treatment) (n = 105) included aerobic, strength, balance, and functional training. The active control group (n = 105) received transcutaneous electrical nerve stimulation and active range-of-motion exercises. Both groups received 2 to 3 home visits from a physical therapist weekly for 16 weeks; nutritional counseling; and daily vitamin D (2000 IU), calcium (600 mg), and multivitamins. Main Outcomes and Measures: The primary outcome (community ambulation) was defined as walking 300 m or more in 6 minutes at 16 weeks after randomization. The study was designed to test a 1-sided hypothesis of superiority of training compared with active control. Results: Among 210 randomized participants (mean age, 80.8 years; 161 women [76.7%]), 197 (93.8%) completed the trial (187 [89.0%] by completing the 6-minute walk test at 16 weeks and 10 [4.8%] by adjudication of the primary outcome). Among these, 22 of 96 training participants (22.9%) and 18 of 101 active control participants (17.8%) (difference, 5.1% [1-sided 97.5% CI, -∞ to 16.3%]; 1-sided P = .19) became community ambulators. Seventeen training participants (16.2%) and 15 control participants (14.3%) had 1 or more reportable adverse events during the intervention period. The most common reportable adverse events reported were falls (training: 6 [5.7%], control: 4 [3.8%]), femur/hip fracture (2 in each group), pneumonia (training: 2, control: 0), urinary tract infection (training: 2, control: 0), dehydration (training: 0, control: 2), and dyspnea (training: 0, control: 2). Conclusions and Relevance: Among older adults with a hip fracture, a multicomponent home-based physical therapy intervention compared with an active control that included transcutaneous electrical nerve stimulation and active range-of-motion exercises did not result in a statistically significant improvement in the ability to walk 300 m or more in 6 minutes after 16 weeks. Trial Registration: ClinicalTrials.gov Identifier: NCT01783704.

Bone grafts are the second most common tissue transplanted in the United States, and they are an essential treatment tool in the field of acute and reconstructive traumatic orthopaedic surgery. Available in cancellous, cortical, or bone marrow aspirate form, autogenous bone graft is regarded as the gold standard in the treatment of posttraumatic conditions such as fracture, delayed union, and nonunion. However, drawbacks including donor-site morbidity and limited quantity of graft available for harvest make autograft a less-than-ideal option for certain patient populations. Advancements in allograft and bone graft substitutes in the past decade have created viable alternatives that circumvent some of the weak points of autografts. Allograft is a favorable alternative for its convenience, abundance, and lack of procurement-related patient morbidity. Options include structural, particulate, and demineralized bone matrix form. Commonly used bone graft substitutes include calcium phosphate and calcium sulfate synthetics-these grafts provide their own benefits in structural support and availability. In addition, different growth factors including bone morphogenic proteins can augment the healing process of bony defects treated with grafts. Autograft, allograft, and bone graft substitutes all possess their own varying degrees of osteogenic, osteoconductive, and osteoinductive properties that make them better suited for different procedures. It is the purpose of this review to characterize these properties and present clinical evidence supporting their indications for use in the hopes of better elucidating treatment options for patients requiring bone grafting in an orthopaedic trauma setting.

Recent estimates suggest an annual incidence of greater than 125,000 femoral neck fractures. Surgical treatment is indicated for the majority of these fractures, which are estimated to double by the year 2050. Most displaced femoral neck fractures in elderly patients are treated with arthroplasty secondary to high complication rates associated with internal fixation. Traditional implants used for internal fixation, typically in elderly patients with stable fracture morphology and younger patients regardless of morphology, include the sliding hip screw (SHS), with or without a supplemental anti-rotation screw, and multiple cancellous lag screws. Complications have been reported with both of these fixation techniques, especially as they apply to treating displaced femoral neck fractures in the elderly. Yet, complications of nonunion, loss of fixation and osteonecrosis, among others, still frequently occur in stable patterns of femoral neck fracture treated with internal fixation. Accordingly, additional implants have been designed recently to improve outcomes and avoid such complications in this population. The Targon Femoral Neck Plate (Aesculap, Tuttlinger, Germany) has been used in Europe for the treatment of both displaced and nondisplaced femoral neck fractures by combining a side plate and multiple cancellous lag screws. Multiple studies have shown superior rates of both nonunion and osteonecrosis when compared to the SHS and multiple cancellous screws in both displaced and nondisplaced femoral neck fractures. This article details the design rationale, surgical technique and early postoperative results of a new hybrid implant used for the treatment of both displaced and nondisplaced femoral neck fractures.

PURPOSE: Indications for removing orthopedic hardware on an elective basis varies widely. Although viewed as a relatively benign procedure, there is a lack of data regarding overall complication rates after fracture fixation. The purpose of this study is to determine the overall short-term complication rate for elective removal of orthopedic hardware after fracture fixation and to identify associated risk factors. MATERIALS AND METHODS: Adult patients indicated for elective hardware removal after fracture fixation between July 2012 and July 2016 were screened for inclusion. Inclusion criteria included patients with hardware related pain and/or impaired cosmesis with complete medical and radiographic records and at least 3-month follow-up. Exclusion criteria were those patients indicated for hardware removal for a diagnosis of malunion, non-union, and/or infection. Data collected included patient age, gender, anatomic location of hardware removed, body mass index, ASA score, and comorbidities. Overall complications, as well as complications requiring revision surgery were recorded. Statistical analysis was performed with SPSS 20.0, and included univariate and multivariate regression analysis. RESULTS: 391 patients (418 procedures) were included for analysis. Overall complication rates were 8.4%, with a 3.6% revision surgery rate. Univariate regression analysis revealed that patients who had liver disease were at significant risk for complication (p=0.001) and revision surgery (p=0.036). Multivariate regression analysis showed that: 1) patients who had liver disease were at significant risk of overall complication (p=0.001) and revision surgery (p=0.039); 2) Removal of hardware following fixation for a pilon had significantly increased risk for complication (p=0.012), but not revision surgery (p=0.43); and 3) Removal of hardware for pelvic fixation had a significantly increased risk for revision surgery (p=0.017). CONCLUSIONS: Removal of hardware following fracture fixation is not a risk-free procedure. Patients with liver disease are at increased risk for complications, including increased risk for needing revision surgery following hardware removal. Patients having hardware removed following fixation for pilon fractures also are at increased risk for complication, although they may not require a return trip to the operating room. Finally, removal of pelvic hardware is associated with a higher return to the operating room.

The diagnosis and treatment of ankle fractures has evolved considerably over the past two decades. Recent topics of interest have included indications for operative treatment of isolated lateral malleolus fractures, need for fixation of the posterior malleolus, utilization of the posterolateral approach, treatment of the syndesmosis, and the potential role of fibular nailing. In this update, we concisely review these topics and what to expect in the future literature.

OBJECTIVES: To document the complications among obese patients who underwent surgical fixation for intertrochanteric femur (IT) fractures and to compare with nonobese patients. DESIGN: Retrospective cohort study. SETTING: Four level I trauma centers. PATIENTS: 1078 IT fracture patients. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Patient and fracture characteristics, surgical duration, surgical delay intraoperative and postoperative complications, inpatient mortality, and length of stay. METHOD: A retrospective review at 4 academic level I trauma centers was conducted to identify skeletally mature patients who underwent surgical fixation of intertrochanteric fractures between June 2008 and December 2014. Descriptive data, injury characteristics, OTA fracture classification, and associated medical comorbidities were documented. The outcomes measured included in-hospital complications, length of stay, rate of blood transfusion, change in hemoglobin levels, operative time, and wound infection. RESULTS: Of 1078 unique patients who were treated for an IT fracture, 257 patients had a Body mass index (BMI) of 30 or greater. Patients with a high BMI (≥30) had a significantly lower mean age (73 vs. 77 years, P < 0.0001), higher percentage of high-energy injuries (18% vs. 9%, P = 0.0004), greater mean duration of surgery (96 vs. 86 minutes, P = 0.02), and higher mean length of stay (6.5 vs. 5.9 days, P = 0.004). The high-BMI group (n = 257) had significantly higher percentages of patients with complications overall (43% vs. 28%, P < 0.0001), respiratory complications (11% vs. 3%, P < 0.0001), electrolyte abnormalities (4% vs. 2%, P = 0.01), and sepsis (4% vs. 1%, P = 0.002). Patients with BMI ≥ 40 had a much higher rate of respiratory complications (18%) and wound complications (5%) than obese (BMI: 30-39.9) and nonobese patients (BMI < 30). CONCLUSION: Intertrochanteric hip fracture patients with a BMI of >30 kg/m are much more likely to sustain systemic complications including respiratory complications, electrolyte abnormalities, and sepsis. In addition, morbidly obese patients are more likely to sustain respiratory complications and wound infections than obese (BMI: 30-39.9 kg/m) and nonobese patients (BMI: < 30 kg/m). The findings from this study can help direct surgeons in the counseling to obese patients and their family, and perhaps increase hospital reimbursement for this group of patients.
